  • Patent number: 9810160
    Abstract: The disclosure relates to a method for determining a temperature in a pressurized flow path of a gas turbine comprising the steps of sending an acoustic signal from an acoustic signal emitting transducer across a section of the pressurized flow path, detecting the acoustic signal with a receiving transducer, measuring the time needed by the acoustic signal to travel from the acoustic signal emitting transducer to the receiving transducer, calculating the speed of sound, and calculating the temperature as a function of the speed of sound, the heat capacity ratio (?) and a specific gas constant (Rspec) of the gas flowing in the pressurized flow path. Besides the method, a gas turbine with a processor and transducers arranged to carry out such a method is disclosed.

  • Publication number: 20160011030
    Abstract: A method is provided for measuring the mass flow of a stream of a gaseous medium of elevated first temperature flowing through a specific pipe. The method includes providing a reference stream of the gaseous medium with a known mass flow and a second temperature being substantially lower than the first temperature. The method further includes mixing the reference stream with said stream of a gaseous medium of elevated first temperature flowing through said specific pipe. The measure resulting temperature of the mixture of the reference stream and said stream of a gaseous medium of elevated first temperature flowing through the specific pipe is measured.

  • Publication number: 20030236169
    Abstract: For producing a superconducting circuit, a film (12) consisting of a cuprate superconductor material is generated on a substrate (13), wherein the superconductor material is in the superconducting state at an operating temperature of the superconducting circuit to be produced, and then the film is irradiated by projecting an energetic ion radiation onto the film through a mask (11) positioned at a distance from the film and protecting selected areas of the film from being irradiated, the mask comprising a structure pattern transparent to the ion radiation but otherwise opaque to the ion radiation. Areas (14) not protected by the mask are irradiated with an ion dose being sufficiently low to avoid degradation of the crystal structure of the first film but being sufficient to inhibit superconductivity of the film with respect to the operating temperature; ion doses are preferably in the range of 0.8·1015 and 2·1015 ions/cm2 or below.

  • Patent number: 6557268
    Abstract: The invention relates to a dryer (1) for drying continuously conveyed products, e.g. a warp, comprising essentially a first dryer array (2) and a second dryer array (3). A passage (4) for passing through the product (W) is formed between the dryer arrays (2, 3). The second dryer array (3) is configured in such a way as to be able to move in relation to the first dryer array (2). When the dryer (1) is in stop position (S), the second dryer array (3) is disposed relative to the first dryer array (2) in such a way that the cross section of the passage (4) is bigger than in the operating position (B).

  • Patent number: 6548570
    Abstract: A radiation shielding material is manufactured from an elastomer that is blended with a radiation-absorbing filler material. The filler material comprises a powder of a metal with a high atomic member, or compounds thereof. The filler material is represented by more than 80 percent weight and has a grain size distribution in the range of 20 &mgr;m to 120 &mgr;m. The filler material is mixed with a loading material in powdered form. That mixture is kneaded with the elastomer within a mixer while the temperature is maintained below 180° C. The kneaded mixture is cooled and then cut into strips. The strips are passed through a strainer having a mesh width of between 5 &mgr;m and 1000 &mgr;m. The strained strips are then formed into a foil.
